Crystal structure of Junin virus nucleoprotein

Structural highlights

4k7e is a 1 chain structure with sequence from Junin virus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	N (Junin virus)
Resources:	FirstGlance, OCA, RCSB, PDBsum

Function

[Q6IVU2_JUNIN] Encapsidates the genome, protecting it from nucleases. The encapsidated genomic RNA is termed the nucleocapsid (NC). Serves as template for viral transcription and replication. The increased presence of protein N in host cell does not seem to trigger the switch from transcription to replication as observed in other negative strain RNA viruses (By similarity).[PIRNR:PIRNR004029]

Publication Abstract from PubMed

Junin virus (JUNV) is identified as the etiological agent of Argentine hemorrhagic fever (AHF), which leads to a serious public health problem with approximately five million people at risk. It is treated as a potential bioterrorism agent for its rapid transmission by aerosols. JUNV is a negative-sense single-stranded RNA (-ssRNA) virus that belongs to the genus Arenavirus within the family Arenaviridae and its genomic RNA contains two segments encoding four proteins. Among these proteins, the nucleoprotein (NP) has essential roles in viral RNA synthesis and immune suppression, but the molecular mechanisms are only partially understood. Here, we represent a 2.2 A crystal structure of the C-terminal domain of JUNV NP. This structure shows high similarity with the Lassa fever virus (LASV) NP C-terminal domain. However, both the structure and function show differences compare to the LASV NP. This study extends our structural insight into the -ssRNA virus nucleoproteins.
